Dr. Whidden Fairfax VA - Whenever any new invention is unveiled to the world, a stunning piece of new technology is made that instantly changes everything. There's certainly a lot of redesigning and experimenting when it comes to inventions, but it takes a lot longer time. Every invention has problems, and it might not be until some other inventor comes along that they get solved. Here are some inventions that changed the course of the world.

1. Great inventions that changed
or could change the world
Dr. Whidden Fairfax VA

2. Why we have chosen this problem
• Nowadays we hear from every where that it is
only one step to the end of the world, that
everything the mankind has done and
invented, leads to the destruction of human
civilization.

3. So we decided
̶ to examine the problem from different sides;
̶ to analyze and compare the most famous,
greatest and unusual inventions.

4. Television (1920s)
• The invention that swept the world
and changed leisure habits for
countless millions was pioneered by
Scottish-born electrical engineer John
Logie Baird. It had been realized for
some time that light could be
converted into electrical impulses,
making it possible to transmit such
impulses over a distance and then
reconvert them into light.
Computer (20th Century)
• The computer has been another life-
transforming invention. British
mathematician Charles Babbage designed
a form of computer in the mid-1830s.
Now, a whole generation has grown up
with calculators, windows, icons,
computer games and word processors,
and the Internet and e-mail have
transformed communication and
information.

5. Motor Car (Late 19th Century)
• With television, the car is probably the
most widely used and most useful of all
leisure-inspired inventions. German
engineer Karl Benz produced the first
petrol driven car in 1885 and the British
motor industry started in 1896. Henry Ford
was the first to use assembly line
production for his Model Т car in 1908.
Like them or hate them, cars have given
people great freedom of travel.
Airplane (Early 19thCentury)
• The plane was the invention that
helped shrink the world and brought
distant lands within easy reach of
ordinary people. The invention of the
petrol engine made flight feasible
and the American Wright brothers
made the first flight
in 1903.

6. Photography
(Early 19thCentury)
• Leonardo da Vinci had described the
camera obscura photographic
principle as early as 1515. But it was
not until 1835 that Frenchman Louis
Daguerre produced camera
photography. The system was
gradually refined over the years, to
the joy of happy snappers and the
despair of those who had to wade
through friends' endless holiday
pictures.
Telephone (1876)
• Edinburgh-born scientist Alexander
Graham Bell patented his invention
of the telephone in 1876. The
following year, the great American
inventor Thomas Edison produced
the first working telephone. With
telephones soon becoming rapidly
available, the days of letter-writing
became numbered.

7. Electricity (19th Century)
• The name came from the Greek word for amber
and was coined by Elizabeth I's physician
William Gilbert who was among those who
noticed that amber had the power to attract light
objects after being rubbed.
• In the 19th century such great names as
Michael Faraday, Humphrey Davy, Alessandro
Volta and Andre Marie Ampere all did vital
work on electricity.

8. Comparative characteristics of the
best and worst inventions of
humanity
The best inventions:
• Bike(59%)
• transistor (8%)
• Electromagnetic induction(8%)
The worst inventions
• Weapon (35%)
• Cell phone (17%)
• Nuclear energy(9%)
• TV (9%)
• Cigarettes(6%)
• Fast food(3%)
• PC (6%)
• radio(5%)
• Internet (4%)

9. The most ridiculous inventions of
the 20th century
• 5. In 1954, spectacles for blind people were patented in
Britain, but during the presentation of the invention several
people were injured.
• 4. In 1970 American physicist Robert Creek announced the
establishment of an apparatus capable of taking samples of
soil from ...the Sun –a sun walker. Creek spent about $ 1.5
million for this invention .
• 3. In 1972, the Spanish cameraman Pinchot Jimenez tried to
make the instrument for blowing out a film.

10. • 2. In 1985, in France, a device for wine tasting in the
cup was patented. It is poured the wine, and after a
few seconds light comes on the dashboard .
• 1. “Four-legged” tights. It is assumed that when a
stocking is torn, a woman will hide it in the special
pocket on the belt and get another stocking.

11. Conclusion
• During the existence of human civilization people
invented different things ; they were useful ,harmful
or ridiculous.
• Each invention has both positive and negative sides,
so we can’t claim that something is only useful but
another one is not.
• The worst invention that can lead our world to the
у end is a weapon.
